TERMINAL CASE.

Application filed August 15, 1925. Serial No. 50,365.

This invention relates to an improved form of terminal case or blockhaving therein a series of conductor terminals, each being insulatedfrom the other and so arranged that the various leads which areconnected to the terminals willalso be insulated from each other and maybe properly designated to indicate the leads.

One of'the objects of the invention is to provide a case or block of theabove mentioned type which is so'constructed thatthe terminals for theleads are not only insulated from each other but are protected from theweather conditions.

Another object of the invention is to so construct the device that theindicating la bels, writing. strips or markers areeasy of access andreadily seen.

Other objects of the invention will appear from the hereinafterdescription and claims.

In the drawing which forms a part of this specification v Fig. 1 is aplan view of the terminal casing or block embodying my invention, partsthereof being broken away.

Fig. 2 is a side View thereof, a portion being broken away.

Fig. 3 is a section on line 33 of the leads being shown.

Fig; 4 is a perspective View showing a Fig 2,

v terminal bar.

Inventions of this class are made up to receive either four, eight ortwelve pairs of leads but in the present application the deviceillustrated and described is adapted for a maximum of eight pairs ofleads.

The body of the device may be made up of insulating parts such as platesor slabs secured together in ways well known in the art, but thepreferred form is an integral casing or block which is made of anysuitable moldable insulating materialand may thus be pressed up to thedesired form in dies by methods well known in the art.

As clearly indicated in the drawings the casing or block is made of abase 10 which is provided with a series of inclined or slopingtransverse partitions 11, the upper corners of which are rounded, asshown, in order to avoid sharp projections. In this instance nine ofsuch partitions are provided for a terminal casing constructed toreceive eight pairs of leads.

These ridges 12 act 'to dividebar is provided With'screw-threaded holes14:

and 15'Ito receive the screw terminals 16 and 17 by means of which theleads 20 and 21 are properlysecured. At the center of'the bus-bar-aroughened area 22 is provided for the purpose of affording anchoringengagement with the bottom of the longitudinal ridges 12 so as toprevent the bus-bar from being radially dislodged. Other anchoring meansmay be used for this purpose such as pins or cavities or any unevensurface, all well known-in the art. a i 1.

The longitudinal ridges are preferably flat on top as at 23and lead fromthe upper surface of one horizontal partition to a point near the middleof the partitionnext below as clearly shown in the drawing.

A marking strip 30, consisting preferably of bristol board or strongwhite paper is secured to the upper face'ofeachtransverse or heavy paperinto the surface of the mold able insulating material such as used informing'the terminal casing or block so that the two surfaces, those ofthe partition and the card, willbe in the same plane. 7

' The transverse partitions 11 are inclined as shown for the purpose offorming sloping surfaces or eaves for carrying away rain and thusprotect the terminals from the elements of the weather. The uppersurface of the inclined transverse strips also pre sent as above stateda favorable position for the marking strips so that they will not onlybe readily seen but easily reached.

Each end of the casing is provided with a heavy transverse strip ofinsulating material through which rivets or screw holes no i he isenabled to plainly mark the leads on the respective marking strips.

As iswell known, the ends of the leads may be fastened very readily bymeans of binding screws to the conductor plates or bars and asthey aresituated in the respec tive chambers or cells having walls of insulatingmaterial they are safe from injury and from short circuitinga As changesof construction could be made within the scope of my invention, it isintended that all matter contained in the above description or shown inthe accompanying drawing, be interpreted as illustrative and not in alimiting sense;

Having now described'my invention, what claim as new and desire tosecure by Letters Patent is: v

1. A terminalcase consisting of a body of insulating material providedwith a series of inclined transverse parallel partitions projecting fromafface thereof, each partition extending entirely across the case andconnected to each other intermediate of their ends with longitudinallydisposed braceplates, each of said plates extending respectively fromthe upper surface of one partition to a point near the middle of thepartition next below to form pairs of chambers or cells insulated fromeach other, and a conductor plate o bus bar provided with terminalscrews at each end thereof secured to the bottom of each formedrespectively between the trans verse partitions, each terminal beingsituated in a'chamber or cell of a pair, the transverse partitions beingeach provided with an uninterrupted exposed upper surface throughout thewidth ofthe case.

2. A terminal case consisting of a body ofmolded insulation havingfastening means at each end, a plurality oftransverse inclined parallelpartitions extending entirely across the body of the case formingrecesses therebetween, a longitudinally disposed central row of braceplates dividing each of said recesses into apair of cells, one cell oneach side of a brace plate, a conductor plate provided With a-t'erminalscrew in each cell, said'plate being secured to the bottom of eachrecess, and a marking strip secured to the upper face of each lower-mostpartition, said strip'extending uninterruptedly across spacethe'body'from one cell to-the other cell of each pair.
